Aerospace structures are different from other structures due to the difference in the required properties for an aerospace application. The primary motivation of this kind of structure lies in its lightweight nature, ... -
Uncertainty Modeling For River Water Quality Control
(2010-08-30)Waste Load Allocation (WLA) in rivers refers to the determination of required pollutant fractional removal levels at a set of point sources of pollution to ensure that water quality standards are maintained throughout the ... -
Uncertainty Quantification in Flow and Flow Induced Structural Response
(2018-07-23)Response of flexible structures — such as cable-supported bridges and aircraft wings — is associated with a number of uncertainties in structural and flow parameters. This thesis is aimed at efficient uncertainty quantification ... -
Understanding And Supporting Conceptual Design Synthesis Of Multiple State Mechanical Devices
(2015-08-07)Conceptual design synthesis is part of the conceptual phase of the design process, which focuses on creating alternative, candidate solutions. Conceptual design phase has the greatest influence on the cost and characteristics ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Understanding Context In Designing
(2009-05-25)Everything around us that is not a simple untouched piece of nature has been designed by someone. Human society has found a great refuge in these designed objects or the artefacts, and thus has adapted vociferously to their ... -
Understanding deformation mechanisms in the Hall-Petch breakdown regime of Ni-W alloys
The substantially higher strengths of nanocrystalline metals has been to attributed to the well-known Hall-Petch relationship σ= σ_o+k_HP d^(-1/2) where 𝜎 is the yield stress, 𝜎𝑜 is the lattice friction stress, 𝑑 is ... -
Understanding design communication in internet-enabled remote synchronous collaborative design in the early stages of design
Remote synchronous collaborative design necessitates designers to carry out the design process using web-based real-time communication applications for collaboration with co-designers. Design communication involves exchanging ... -
Understanding failure in heterogeneous materials
The failure of heterogeneous materials is a practical problem that occurs in several diverse applications. Material heterogeneity can arise from porosity (e.g., due to some processing history), variation in continuum-scale ... -
